Here’s a totally awesome image of an enormous supertanker speeding along just off the coast of Rio de Janeiro. Only ships above 250,000 tonnes are considered true supertankers, and due to their massive size and weight, their stopping distances are generally measured in miles. They’re also capable of carrying around two million barrels of oil. It all seems completely unbelievable somehow, and yet Wikipedia tells us it’s true… Thanks to Gus.
